Application filed April 2 5, 1927. Serial No. 186,336.

This invention relates to improvements in smoke houses, particularlyofthe type employed for curing meat, fish and like-commodities bysubjecting the same to a dense smoke or smudge from suitablecombustibles, and aims primarily to providea smoke house especiallydesigned to use any kind of fuel for maintaining a smudge to cure thecommodity placed therein and wherefrom the noxious combustion productsof the fuel are carried 0H without contacting withor contaminating suchcommodity.

Contemplated by the present invention is a smoke house embodying 'acombustion chamber or fire box; a smudge chamber separated andsealedfrom said fire box; a curing or smoking chamber for the commodities tobe cured communicating with said smudge chamber; a grating or grilleseparating the smudge and curing chambers; a fiue for combustionproducts leading upwardly from the combustion chamber through the smudgechamber; a transversely disposed super-heatingflue wherewith thecombustion chamber "flue is connected which'extends through and projectsat one end thereof from the smudge chamber; a flue for the smoke fromthe smudge chamber leading from the upper end of the curing chamber;means for supporting within the curingc-ha'mber the commodities to betreated; and means to permit of rapid and ready access to the severalchambers of the smoke house, all of which are important features of theinvention and are to 'be'correlated in the broad aim of enhancing the'efficiency of the apparatus for general use.

The above,and additional features and objects which will be morespecifically treated are attainedby such means as are shown in theaccompanying drawings, described in the following specification and thenmore clear- 1y pointed out in the claims, which are appended hereto andform'part of this application. 1

WVith reference to the drawings, in Which there is illustrated oneembodiment of the invention, and throughout the several views of whichlike characters of reference designate similar parts:

' Figure 1 is a longitudinal vertical medial section of a smoke housecomprehended by the present invention, and

Fig. 2 is a fragmentary vertical transverse section of the same takenthrough 22 of way of illustration.

Fig. 1, certain parts thereof being shown' in elevation for clarity ofillustration.

Beforetakin-g up the detailed description of the drawings, a generalexposition of the specific purposes, functions and advantages of thesmoke house evolved by the present in ventlon will be undertaken, which,while it is primarily and especially designedf'forsmoking or curing meatand fish is also adaptableand suitable for treating other commodities ina like manner when necessary or desired." Heretofore, it has beencustomary in fabricating a smoke house-toconstr uct the same with acommon smudge and curing chamber only, which necessitated burning fuelhaving no noxiousfumes or gases to contaminate the commodity beingcured, actual experience has demonstrated in many in.- stances that suchmethods are inconvenient, wasteful and ineflicient. Wherefore, it is aprimary object of p the present invention to fabricate a smokehouse-having afire box or combustion chamber separated and sealed fromthe intercommunicating smudge and curing chambers thereof, wherein anykind of fuel may'be burned such as coke, coal, oil, gas or the llke, for1gn1t1ng and maintaining a smudgeof suitable combustibles within saidsmudge chamber, and wherefrom thenoxious gases or fumes from said fuelsare carried off- 111 such a manner as to prevent the same from coming incontact with the commodity being treated in order that the latter maynot be contaminated 01" detrimentally affected thereby, aswill bemanifest and apparent; A further and essentially important feature ofthe present invention is to produce and'maintain asmokehouse smudge in amore convenient, economical and efiicient manner than has'heretoforebeen attamed. In the present instance the smoke house "disclosed" isequipped with oil burning apparatus, but, it

is to be understood that other fuels maybe used, without departing fromthe spirit. of

the invention or the benefits-derivable there A from, the presentshowing being merely by jBeginning the more detailed description of theapparatus by reference to the drawing,

are supported or rest upon the basement floor 4 andlextend upwardlytherefrom through the main floor 5, and inasmuch as: the smoke housesare identical in construction, a description of one. will sufiice forall.

The smoke house 6 is sub-divided into a-se ries of chambers comprising abrick-lined combustion chamber or fire box 7, a smudge chamber 8 and acuring or smokingchamber 9. The combustion chamber 7 and smudge chamber8.are separated from-each otherby a horizontallydisposed brick-wall10or=bya metal =.plate and, to effiect a positive sealingandaseparationof such-chambers from each other, a layer of fire cement1.l is spread upon the upper surface-of the separatingwall 10, whereatitalso serves and functions-as a floor I for the-smudge-cha1nberi8.

-Moun-ted:upon1 the forward wallof the combustion chamber 7 in anyconvenient manner-is an oil burner 12, ofrany well known type, thediseh-argenozzle or burner tip 13 of which extends: into said combustionchamber throughhan aperture llformed in said ilorthrough-"the smudgechamber Sand iitsupper end is: curved forwardly and rigidly connected:to an enlarged transversely disposed fiue{16', wl1-iehextendsthrouglrand is-:common to allof thesmudge chambersof theseriesyof.smoke -houses, saidfl'ue 16. beingprimarily. designed .andintended to; utilize the heat of; the.:combustiony products passingtherethrough for superb-eating; the-- smudge chamber 8: and materiallyincreasing the temperature of. tlie curing; chambers .associatedthGI'G'lVlthJ The discharge end of the fine 16 extends beyond'ztherendsmudge chamber. 8 of the series. and is connected to a chimney, notshowin -'bviously-,rtherefore, the

An -opening *18formed in! the forward wallof the smudge chamber 8 and normally closed by aydoor 19 provides readyand-'convenient aeoess to said smudge chamber for replenishing the samewith combustible matter. I

'Interposedfland suitably supportedi between the smudge chamber 8 andthe curing or smoking chamber 9 for separating the same, whilepermitting of ready communication therebetween, is agratingor grille 20,which latter .is preferably disposed in the horizontal plane of the mainfloor 5, and serves andfunctions to intercept any of thesuspendedcommodities being treated in the curing chamber, which mayaccidentally drop from their supports and prevent same from falling.into the-smoldering mass of combustibles 17 as will be obvious andapparent. Centrally and fixedly: securedto the rear walliof the curingchamber- 9, adjacent its upper end and extending perpendicularlytherefrom beyondthe. forward wall of said chamber, is .a track 21rigidly I secured .at its opposite orouterzend to verticallyv disposedsupport22.
